Filed: 1971-07-23
Abstract: 1378144 Data processing systems INTERNATIONAL COMPUTERS Ltd 20 July 1972 [23 July 1971] 34683/71 Heading G4A An arrangement which may be used for interconnecting different types of peripheral machine with a processor includes a program memory 210 providing instructions which control the selection of a single group of inputs from a plurality of inputs and the selection of a single group of outputs from a plurality of outputs, and a logic network which determines the response on the outputs provided to the selected inputs in accordance with the stored program. Block 230 is divided into two sets of 16 registers each of 12 bits. One or both of multiplexers 234, 235 can be selected by an instruction to pass the contents of the addressed register in the associated set or the data field of an instruction in buffer 217 or predetermined bit patterns such as all 1 or all 0 to logic unit 250 which performs the basic operations of addition and comparsion. The output of logic unit 250 is supplied to an output block, Fig. 3 (not shown) over cable 254 and may be inserted in a selected register in block 230 via multiplexer 205. The destination register in block 230 may be one of the source registers. The necessary switching operations are controlled by a control block 220 which receives the order code of an instruction in buffer 217. The input to register block 230 may also be supplied by the data field of an instruction in buffer 217 or as the result of a masked read operation on an input block, Fig. 1 (not shown), in which a 3-bit field (41) of the instruction selects 12 of 96 inputs for masking with the 12-bit data field (42) of the instruction, and the resulting masked word is stored, via multiplexer 205, in a register selected by a S-bit field 43 of the instruction. In an operation requiring two registers in block 230 to be addressed, instruction fields 41, 43 are combined as two 4-bit addresses to select a register from each set of block 230. The output block utilizes the 12-bit word from logic unit 250 as follows: one group of 4-bits is decoded to select one of 16 groups of four gates which are supplied with a second group of 4-bits constituting a mask for the remaining group of 4-bits to control the setting of a corresponding group of 4 bi-stables. In this manner up to four of a set of 64 outputs can be altered at a time. The instruction memory is sequentially addressed by a counter 212 but program jumps can be made by presetting counter 212 by the output of multiplexer 205. Specification 1,378,143 is referred to.
